`import pyg_lib` fails due to `OSError: dlopen ... (no such file)` on macOS

[ryrl9703]

🐛 Describe the bug

I have installed the torch and torch_sparse and pyg_lib packages successfully, but when I import torch_sparse just report error as folling:

   OSError: dlopen(/Users/wakala/venvs/versions/3.12.2/torch/lib/python3.12/site-packages/libpyg.so, 0x0006): Library not loaded: /Library/Frameworks/Python.framework/Versions/3.12/Python

Environment

• pyg-lib version: 0.4.0+pt23
• PyTorch version: 2.3.0
• OS: MacOS 14.4.1 (23E224)
• Python version: 3.12.2
• CUDA/cuDNN version:
• How you installed PyTorch and pyg-lib (conda, pip, source): pip
• Any other relevant information:

I think you should try a conda... it's difficult for Mac to set py environment with pip.

Do you mind to clarify how you installed PyTorch and pyg-lib? It runs fine for me on macOS M2.

Hello, I have the same problem in macOS M2.

• pyg-lib version: 0.4.0
• PyTorch version: 2.3.0
• OS: macOS 14.5
• Python version: 3.11.9
• CUDA/cuDNN version: None(cpu only)
• How you installed PyTorch and pyg-lib (conda, pip, source): pip (via pipenv)
• Any other relevant information:

First, I installed pyg_lib via pipenv.

pipenv run pip install torch~=2.3.0 torch-geometric~=2.5.2 --no-cache-dir
# https://pytorch-geometric.readthedocs.io/en/latest/install/installation.html
pipenv run pip install pyg_lib torch_scatter torch_sparse torch_cluster torch_spline_conv \
  -f https://data.pyg.org/whl/torch-2.3.0+cpu.html \
  --no-cache-dir

Then, I ran the following command and got same error.

python -c "import pyg_lib; print(pyg_lib.__version__)

Somehow pyg-lib on macOS expects that you have a proper system Python installed. The easiest way to unblock for now is to simply install a system Python 3.11/3.12 version (whatever your error message says) from here.

A less simple solution to this problem is to soft link /Library/Frameworks/Python.framework/${version} to a Python bin (e.g. the Python of the conda environment where you install pyg-lib) which has the same version. In this way, no redundant system-level Python will be installed, though the soft link now is environmentally dependent.

It seems that even installing from Python official solves it, but the error message changes somewhat @rusty1s.

It seems that is still expecting packages elsewhere. I'm running this on M3 Pro Mac, using Python3.11.8, torch 2.3.0, torch_geometric >=2.5.3.

I'm thinking of doing @Linnore proposal for now.
